There is an issue with the new resigned Jar files and Java 5.0 running on ITM 6.2.3 . After resigning Jar files check that the JRE in-use is the correct version as Java version 5.0 dose not work. Where you have ITM 6.2.3 still running with JRE 5.0, you will need to update the JRE to version 6.0 or later. If you have more than one version of Java running then follow the steps below to select the correct Version of Java to run. 1. Go to Start -> Control Panel and Start the Java control Panel Applet. 2.

Updates for the Java webstart client crash issues. ( Please refer my previous blogs - Java 6u65 and Java 7u45 ) The failure is caused by new security enforcement of JRE runtime parameters in Java Webstart deployed applications jnlp files. This security change was introduced with Oracle JRE 6u65 and JRE 7u45. The APAR IV51394 is opened to resolve this problem and provisional fixes for the following releases will be tentatively available on Friday, Nov 15th: 6.3.0-TIV-ITM-FP0001, 6.3.0-TIV-ITM-FP0002 6.2.3-TIV-ITM-FP0001,...

Oracle added same security updates in Java 1.7u45 that I mentioned in my previous blog into Oracle Java 1.6u65. As a result, Java webstart client will fail to start with Oracle Java 1.6u65. The only work around at this point is to use Oracle Java 1.6 u51 or less.The customer can also use the TEP browser client as an alternative. We opened an APAR IV51394 to resolve this issue but we don't have ETA yet. We'll update the progress when we have a solid plan.

As of Oracle Java 1.7.0u45 the TEP java webstart client failed to start. The following link talks about the new enforcement of Java runtime parameters in jnlp files. https://bugs.openjdk.java.net/browse/JDK-8023821?focusedCommentId=13377692&page=com.atlassian.jira.plugin.system.issuetabpanels%3acomment-tabpanel#comment-13377692 The only work around at this point is to use Oracle Java 1.7.0u40 or less.The customer can also use the TEP browser client as an alternative.
